Prohibit Entry of Alphabetic Characters “I” and “O” 

in a DoDAAC/RIC (DoDAAD)

1. ORIGINATING SERVICE/AGENCY AND POC INFORMATION: Enterprise Business 

Standard Office (EBSO), DoDAAD PRC Chair, Tad DeLaney, at 703-767-6885, e-mail: 

DODAADHQ@dla.mil. 

2. FUNCTIONAL AREA: DoDAAD

3. REFERENCE: DLM 4000.25, Defense Logistics Management Standards (DLMS), Volume 

6, Chapter 2, Department of Defense Activity Address Directory.

4. APPROVED CHANGE: Stop the creation of DoDAACs and RICs that contain alphabetic 

characters “I” or “O”, since “I” and “O” were never intended to be used as valid DoDAAC or 

RIC keys. Substantive updates subsequent to PDC staffing are highlighted in green.

a. Overview: This change only affects the Department of Defense Activity Address 

Directory (DoDAAD) Update Application. It prohibits the use of the letters “I” or “O in any of 

the six positions of the DoDAAC or three positions of the RIC primary key. This restriction has 

always existed, but it required the person entering the data to enforce the rule. This change is to 

enforce the rule programmatically. 

b. Background: The alphabetic characters “I” and “O” are easily mistaken for the 

numeric characters “1” and “0”. No DoDAAC or RIC should contain “I” or “O”; however, some 

DoDAACs and RICs presently contain these characters, because the rule was not 

programmatically set. To avoid continuing this problem in perpetuity, the Defense Automatic 

Addressing System (DAAS) must enable an edit in the DoDAAD Update Application to validate 

all six positions of the DoDAAC or three positions of the RIC key, so no new DoDAACs/RICs

containing “I” or “O” will be created. 

5. ROLES AND RESPONSIBILITIES: 

a. DAAS: 

(1) Change the edit for add, change, and delete of the DoDAAC/RIC key field in 

the DoDAAD Update application to search for any occurrence of an “I” or “O” in all six 

positions. 

(2) If “I” or “O is found, the next test is to determine if the DoDAAC/RIC

associated with the entry exists. 

(3) If the DoDAAC/RIC exists, allow the delete to take place. If the change is an

add or edit, issue the error message “Neither DoDAACs or RICs can contain ‘I’ or ‘O’.”

(4) One additional check must be made when creating a DoDAAC from a 

DoDAAC that is already a key in the database. If creating a DoDAAC based on an existing 

DoDAAC, the new DoDAAC key cannot contain the alphabetic characters “I” or “O.” 

b. Enterprise Business Standards Office: 

(1) Revisions to DLM 4000.25 Manuals: None required. The DLM 4000.25 

manuals already document restriction of “I” and “O” in the DoDAAD series table. 

(2) DLMS Data Elements: No changes. 

c. DoD Components and Federal Agencies: 

(1) “I” and “O” are not authorized for use as DoDAAC/RIC keys (within the six

characters that makeup a DoDAAC/RIC). 

(2) Army and Air Force must make the necessary changes to their respective 

DoDAAC applications to mirror these changes to the DoDAAD. 

(3) Non-DLM 4000.25 Series Publications: The changes identified herein must 

be incorporated into the relevant Service/Agency-level DoDAAD management publications, 

including (but not limited to) the following: 

(4) 41 CFR, Federal Property Management Regulations 

(5) U.S. Army: AR 725-50 

(6) U.S. Air Force: AFI 24-230

(7) U.S. Marine Corps: MCO 4400.201, Vol 2

(8) U.S. Coast Guard: COMDTINST M4000.2 

(9) Defense Information Systems Agency: DISA Instruction 270-50-10 

6. ADVANTAGES AND DISADVANTAGES:

a. Advantages: Avoids the confusion of “I” and “O” with numeric values “1” and “0”.

b. Disadvantages: None noted.

7. ESTIMATED TIME LINE/IMPLEMENTATION TARGET: Authorized for immediate 

implementation. Target timeline for DAAS updates to the DoDAAD is 60 days from the 

publication of this DLMS change.
